Publisher's Synopsis
Excerpt from Chemical and Physical Properties of Spoil Banks in the Eastern Kentucky Coal Fields
The spoil bank resulting from strip or open-pit mining is a heterogeneous mass of earth that has physical and chemical properties determined by the rock strata overlying the coal. The material is unique, bearing little resemblance to the original soil mantle, and it sometimes poses difficulties to those attempting revegetation. These difficulties gave rise to our study of spoils from the eastern Kentucky coal fields. In the study we are identifying the chemical and physical characteristics of spoil-bank material and evaluating their influence on plant establishment and growth.
As a first step in understanding spoil material, we have deter mined the chemical and physical properties of spoil samples obtained from six major coal-producing seams in eastern Kentucky. While these samples may not reflect all the conditions to be found on spoil banks, we think they have given us an idea of what scientists can expect to find under field conditions. This report summarizes the results of our comprehensive analyses.
